About this directory and the Michigan rheumatology market
Step 1. Step 2. Match. Boards. Then what?
Then training ends and the page goes blank. The first contract lands in your inbox with terms you have never seen, written by people who do this for a living against someone who has done it exactly never.
Before you compare salary numbers, see how many physician-owned groups actually exist in your specialty and state. Then negotiate from leverage instead of from gratitude.
What other resources point to in Michigan
There are 106 physician-owned rheumatology practices in Michigan, spread across 35 cities. I pulled every one of them from the NPPES NPI Registry, which is the federal database that CMS maintains for active providers. Then I filtered out anything that isn't independently operated. Hospital-employed positions, academic faculty roles, locum agencies, government clinics, they're all excluded. What's left is a clean list of practices where physicians hold actual ownership and make their own clinical decisions.
The reason this matters is that job boards don't distinguish between an independent rheumatology practice and a corporate medical group. They list them side by side, identical formatting, identical apply buttons. But the compensation model, the call schedule, the equity path, and the long-term upside are completely different depending on who owns the practice. This page separates the two. You can work through the list, contact practices directly, and skip the recruiter entirely.
The Michigan rheumatology market in detail

Frequently asked questions about rheumatology in Michigan
How many Rheumatology private practices are in Michigan?
There are 77 physician-owned rheumatology private practices in Michigan, verified against the NPPES NPI Registry. All are independently operated. Hospital-employed, government, corporate, and academic positions are excluded.
What does physician-owned mean?
A physician-owned practice is one where licensed physicians hold controlling ownership of the business entity. This is distinct from hospital employment, corporate medical groups, or private equity-backed practices where non-physician entities control the business.
What does the Corporate-Acquired or MSO-Affiliated flag mean?
The Corporate-Acquired flag means the practice was historically physician-owned but has since been acquired by a corporate entity such as Optum. The MSO-Affiliated flag means the practice uses a Management Services Organization for billing and administration while physicians retain practice-level ownership.
Biologic Infusion Revenue in Michigan Rheumatology Practice
Michigan's physician-owned rheumatology practices include Michigan Rheumatology Consultants (Royal Oak) and West Michigan Rheumatology (Grand Rapids).
What is an NPPES-verified practice?
NPPES is the National Plan and Provider Enumeration System, a federal database maintained by CMS. Every practice in this directory has an active NPI record in NPPES, confirming it is a registered U.S. medical practice.
What is white-bagging and how does it affect rheumatology private practice revenue in Michigan?
White-bagging is a payer policy requiring the drug to be dispensed by a specialty pharmacy and shipped to the physician's office rather than purchased directly by the practice. This eliminates the buy-and-bill drug margin, the practice bills only for administration, not for the drug itself. Brown-bagging requires the patient to pick up the drug from the pharmacy and bring it to the office. Both policies significantly reduce infusion revenue in private rheumatology practices. Ask any prospective practice what percentage of their commercial contracts allow traditional buy-and-bill versus requiring white-bagging.

Key Terms in Physician Contracts
PC (Professional Corporation)
A state-chartered corporation formed by licensed professionals. Physicians use PCs to own and operate their practices with liability separation. Many states require medical practices to be structured as PCs rather than standard LLCs or general partnerships.
PLLC (Professional Limited Liability Company)
A hybrid entity combining LLC flexibility with professional licensing requirements. PLLCs are common for physician-owned practices in states that permit them. They offer pass-through taxation and personal liability protection for non-malpractice claims.
MSO (Management Services Organization)
A non-physician entity that provides administrative infrastructure (billing, coding, EHR support, payer contracting) to physician-owned practices. MSO arrangements let physicians retain clinical and practice ownership while outsourcing back-office operations. Private equity commonly uses MSO structures to influence practice operations without technically owning the medical entity.
NPI (National Provider Identifier)
A unique 10-digit number assigned to every U.S. healthcare provider and organization by CMS. Individual physicians receive a Type 1 NPI; practice entities receive a Type 2 NPI. The NPI is used across all payers for billing and credentialing.
Restrictive Covenant
Any contractual clause that limits a physician's professional activities after leaving an employer. Non-compete clauses are the most common restrictive covenant, but the category also includes non-solicitation clauses (prohibiting contact with former patients or staff) and non-disparagement clauses.
White-Bagging
A payer policy requiring biologic drugs to be dispensed by a specialty pharmacy and shipped to the physician's office, rather than purchased by the practice directly. Eliminates the drug acquisition margin in the buy-and-bill model. Increasingly adopted by commercial payers as a cost-containment strategy.
Biologic Infusion Suite
A dedicated space within a physician office or freestanding facility where intravenous biologic medications are administered under medical supervision. Rheumatology infusion suites generate facility revenue (or drug + administration revenue) separate from physician E&M billing when the practice owns the infusion operation.
